Abstract

A method for monitoring a condition of a rotating element, in particular an electric machine, includes acquiring, by a first sensor, a first measured variable dependent on the rotational position of the rotatable element and outputting a rotation signal corresponding to the first measured variable, ascertaining a clock rate of the acquisition of the first measured variable via a processing unit or via a separate evaluation unit, acquiring, by a second sensor of the rotational speed acquisition unit, a second measured variable different from the first measured variable and outputting a measuring signal corresponding to the second measured variable, adjusting the clock rate of the acquisition of the second measured variable by taking into account the ascertained clock rate of the acquisition of the first measured variable, and using the rotation signal and the measuring signal adjusted to the rotation signal to monitor the condition of the rotating element.
